Abstract

Ultra-fine zinc oxide powders were prepared using ultrasonic method at 60°C with zinc acetate, zinc nitrate and potassium hydroxide solution as precursors. The obtained powders were characterized by means of scanning electron microscope, thermogravimetric analysis, X-ray diffraction and infrared spectroscopy. The crystal structures were investigated based on Rietveld method. The results showed that, zinc oxide powders have hexagonal structure (P6 ₃mc) with particle size in the range of 100-300 nm. The mechanism for the ZnO formation was discussed. The properties of synthesized materials were examined by UV-Vis spectrum and cyclic voltammetry measurement.
